A lot of Black kids get sent to all-Black colleges to connect with what they and their family think is their heritage. Many are middle and upper class and live in the suburbs or better areas of town. They have had good lives but feel they need to connect with their poorer brothers.
The connection is to adopt most of the bad and little of the good, hip hop clothes and speech, a tough attitude and hate for the "man." Colleges are the refuge of the 60's radicals and the ones at Black colleges have some of the worse Black Panther types. Put them and gullible kids together and you get an audience ready to cheer John Dean and his ilk.
Hopefully, when these kids graduate they return to their middle/upper class lives and see that making a buck and being good to family gets them the good life. Some may even see the light and vote Republican.
